sqlserver函數(shù)存儲過程游標(biāo)以及while和if語句的嵌套使用

1、sqlserver函數(shù)，存儲過程，游標(biāo)以及whileif語句的嵌套使編寫這個存儲過程的主要原因是太懶，不愿意每天往表做數(shù)據(jù)，所以就寫了他。不僅僅是學(xué)習(xí)，也是的鍛煉。USE oaerpGO/* Object: StoredProcedure dbo.s_Get_AutoYh Script Date: 02/11/2015 17:17:35 */SET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGO- =- Author: - Create date: - Description: - =ALTER PROCEDURE dbo.s_Get_AutoYhsdtm
